Architects have learned a new respect for an ancient material during the past decade. Concrete has come of age in a variety of ways. Through the use of aggregates, color, form and proportion, concrete has taken on a classic beauty that has convinced an increasing number of architects it is the ideal material for a variety of exterior and interior applications. Concrete was used for a recently completed 54,000 square foot office and plant structure in an industrial park in suburban Milwaukee. It was used for more than just its beauty. Its economy, ease of handling, and several other significant reasons were considered before deciding upon its use. The site for the New Dataforms plant was covered with several feet of uncompacted fill, which posed serious foundation problems. With lumber and labor costs soaring, and prefabricated sections uneconomical, it was decided to "bring the factory to the site." The floor slab was placed first, to provide a working surface. Then forms were built and the plant walls, 5 and one-half inches thick was cast and later tilted into position. The plant walls were cast 5 and one-half inches thick. In order to maintain constant humidity for Dataforms quality control, these walls, too, were insulated. However, for other production requirements, or in other climatic environments, this might be unnecessary. In this installation, the cost of the wall compared favorably with insulated block because the panels could span pier footing to pier footing without additional foundation walls. Since many industrial sites are plagued with similar soil problems, this technique most likely will be used more and more.
